Understanding The Ukraine and Russia Tug of War With Crimea [VIDEOS][POLL]

If you're like me, you try to stay up to date on world events. Only problem is: you end up catching bits and pieces of the latest news, but wonder how did this whole thing come about? 

I found a couple of videos explaining the how this conflict between the Ukraine and Russia has evolved to it's current situation.

So the big question here is, should the U.S. get involved? Personally, I feel that if there are no human rights violated and they aren't asking for us to help them, then why are we sticking our nose in there business? If an area in south Texas decided they wanted to be part of Mexico...would we want Russia coming to us and giving us advise? No! We'd say, get your nose out of our business!

What do you think?
